A water processing system provides prevention of scale formation in both interrupted and recirculating flow operations. The system includes an inlet for receiving an inlet water flow, a magnetizing chamber, and an outlet for providing an outlet water flow. The magnetizing chamber is included in a device that has at least one permanent rod/bar magnet at least partially disposed within the water flow. The magnet has an axis extending between the poles thereof in a direction perpendicular to the flow, so that the magnetizing chamber exerts a magnetic force on scale suspended within the inlet water flow, and so that the suspended scale remains in suspension in the outlet water flow.

Glycine is an organic compound that can be used in the making of a synthetic acid that obviates all the drawbacks of strong acids such as hydrochloric acid. The new compound is made by dissolving glycine in water, in a weight ratio of approximately 1:1 to 1:1.5. The solution is mixed until the glycine is essentially fully dissolved in the water. Once dissolution is complete, hydrogen chloride gas is dissolved in the solution to produce the new compound, which can be referred to as hydrogen glycine. Also disclosed is a method for adjusting the pH of a fluid, the method comprising adding an effective amount of a solution to the fluid for adjusting the pH thereof to a desired level, wherein the solution is prepared by mixing glycine in water to form a glycine solution; and adding hydrogen chloride to the glycine solution.

The invention is a method of remediating water by adding to a quantity of water to be treated a compound or composition that generates hypohalous acid in situ, followed by addition or generation of ammonia to create an excess of ammonia and in turn to accomplish heretofore unachievable benefits and efficiencies.

A desalinating system and method is disclosed. The desalination system comprises using a turbo freeze or fast-cooling process to freeze saline water droplets and separate salt crystals from pure water crystals, wherein said system provides for simultaneous injection of saline water droplets and a chilled refrigerant into a freezing chamber at a slip velocity sufficient to reduce the size of the saline water droplets to an optimal diameter.

A method for recovering NH.sub.4.sup.+ or K.sup.+ ions from manure wastewater is disclosed. The method includes contacting manure wastewater having organic matter and salts with an ion-selective redox material with ionic channels. The manure wastewater reduces the ion-selective redox material which spontaneously takes up NH.sub.4.sup.+ or K.sup.+ ions from the manure wastewater. NH.sub.4.sup.+-or K.sup.+ may be released electrochemically and paired with the simultaneous electrosynthesis of value-added chemicals.

A method is proposed with which a content of formaldehyde in aqueous media that are conducted in a circular flow, in particular within a circular flow of a gas scrubbing installation, can be reduced in an economical and sustainable manner, wherein the formaldehyde in the aqueous medium is chemically bound during a predetermined reaction time in a reaction zone in the course of a formosis reaction in such a way that a release of formaldehyde from the aqueous medium into a gas phase at a temperature of 95 C., an ambient pressure of 1 bar, during a test time interval of 10 min is limited to a concentration of formaldehyde in the gas phase of about 1 ppm or less, wherein the aqueous medium for chemically binding the formaldehyde in the course of the formosis reaction in the reaction zone for the predetermined reaction time is held at a reaction temperature of about 50 C. to about 100 C. and the pH value of the aqueous medium is set to an alkaline pH value in the range of about 11 to about 14.

Described herein is a liquid filtration device is disclosed a vessel for treating an aqueous liquid, wherein the vessel contains a filtration medium and wherein the filtration medium comprises a metal sulfide, wherein the sulfur in the form of a metal sulfide is at least 0.5% by weight of the filtration media.

A magnetic field system for producing an interruptible geometrically patterned magnetic field at a surface, including a surface member including a surface, a magnetic member situated exterior to the surface member, including a geometrically patterned array of magnets, the magnetic member being reversibly mounted in sufficient proximity to the surface member to produce a corresponding geometrically patterned magnetic field extending through the surface, the geometrically patterned array of magnets including magnets selected form the group consisting of permanent magnets, electromagnets, and a combination thereof, the geometrically patterned magnetic field being interruptible by the removal of the magnetic member to a location sufficiently distant from the surface member to withdraw the geometrically patterned magnetic field from the surface, or by the depowering of the powered electromagnets. A gravity separation system for separating and recovering metal particles from a liquid stream of suspended particles to be separated. A method for the gravity separation and recovery of metal particles from a liquid stream with a gravity recovery system.
